The Sedam Springhouse, which may date back to the 1790s, is one of the oldest buildings in the township.[5] Now known as the Delhi Springhouse, the structure stands on land near the stone house Colonel Cornelius Ryker Sedam built in 1796. The house no longer exists, but the springhouse has been restored. The structure protected a natural spring, which supplied water as late as 1937. The springhouse was also used to provide storage for perishable foods.[6]

The township has an area of 10.1 square miles (26.1 km2).[3] Because the township covers the slopes leading down to the floodplain of the Ohio River, the township contains many hills, and its landscape is cut by a number of ravines caused by streams that make the descent.[citation needed]

Delhi Township's average annual rainfall is 41 inches (1,000 mm), received over an average of 82 days, along with 14 inches (360 mm) of snow. Temperatures range from an average July high of 88 °F (31 °C) to an average January low of 15 °F (-5 °C).[7]

The township is governed by a three-member board of trustees, who are elected in November of odd-numbered years to a four-year term beginning on the following January 1. Two are elected in the year after the presidential election and one is elected in the year before it. There is also an elected township fiscal officer,[9] who serves a four-year term beginning on April 1 of the year after the election, which is held in November of the year before the presidential election. Vacancies in the fiscal officership or on the board of trustees are filled by the remaining trustees.

Delhi has various annual celebrations, including the Delhi Skirt Game. The Delhi Skirt Game is a Chicago-style softball game between officers of the Delhi Township Police Department and the firefighters of the Delhi Township Fire Department; the teams consist of male officers dressed in drag. The game is played in Delhi Park on the first Friday of August, with festivities surrounding the game including live music, games of chance, concessions, auctions and fireworks. The Skirt Game benefits needy families of Delhi Township.[11]

Following an 1850s grape blight which destroyed most of the township's vineyards, many growers turned to vegetable farming. On the heels of a successful transition to vegetable farming, growers began to construct greenhouses in order to extend the growing season. At some point in the 1920–1930s, nearly all of the Delhi greenhouse operators began to realize the greater profit potential of growing flowers, and subsequently converted their greenhouses from vegetable-centric operations to growing cut flowers full-time.

The peak of local hothouse agriculture was reached during the late pre-WWII years, when as many as 55 family-run greenhouses operated in the township. Notably, Delhi Township-based greenhouses produced a significant percentage of carnations supplied throughout the United States by this time. In the local region, Delhi Township became known as the "Floral Paradise of Ohio", a trademark phrase that is still featured on modern, official Delhi Township signage.

The importance of greenhouses in Delhi Township was even reflected in the equipment of the Delhi Township Fire Department; as late as 1986, small-diameter fire attack lines were equipped with iron pipe couplings (rather than otherwise ubiquitous National Standard threads) in order to be compatible with the fittings in use on most greenhouse irrigation standpipes of the time. This arrangement permitted firefighters to connect their hoses to the source of water closest to an interior greenhouse fire, eliminating the need to drag (potentially) hundreds of feet of heavy, charged hose connected at the fire apparatus's pump panel outside. In this arrangement, water pressure in the involved greenhouse was boosted by a connection from the pumper to a standpipe connection on the outside of the structure. The requirement to carry a large variety of thread adapters (in order to be compatible with nearby, mutual aid departments), along with the rapid, penultimate decline of hothouse agriculture in Delhi Township led to the complete standardization to National Standard-threaded couplings within the department by the late 1980s.

Today, only a few family-run greenhouses remain—the combined results of a decline in business due to foreign flower imports, as well as the lucrative conversion of greenhouse properties to land made available for residential and commercial development in the post-World War II suburbanization boom.

Story Woods Park, part of the Delhi Park system, has three main paths and is located within woods next to Rapid Run Middle School.

The township operates over 100 acres (40 ha) of park property.[12] Parks operated by the township include Delhi Park, Five-Points Park, and Story Woods Park. Delhi Park, which opened in 1954, is the oldest park in the township. It has nine ball fields, including baseball courts, football fields, soccer fields, tennis courts, and sand volleyball courts. Delhi Park also has the Glen Carder Lodge, four picnic shelters and the "Spray Park." Five-Points Park, a 1.1 acres (0.45 ha) park, has a gazebo and the firefighter's memorial. Story Woods Park, a 40 acres (16 ha) park, has a playground facility, a picnic shelter, toilet facilities, and 2.03 miles (3.27 km) of walking trails. The township also has the Delhi Springhouse, which opened to protect the springs. The springhouse was also used as a source of drinking water and as cold storage for perishable foods. The Great Parks of Hamilton County operates Embshoff Woods, a park which opened in 1982 and consists of 331 acres (134 ha) of protected natural areas.[13]

In November 2007, the township dedicated Veterans Memorial Park in honor of the township's military veterans. Located within the park are the Wall of Honor Monument and the Killed-in-Action Memorial.[14]

The Delhi Press serves the areas of Delhi and Sayler Park, Cincinnati. It is distributed once a week on Wednesdays. An average Delhi Press contains a main article, other articles about the area, school articles, athletic articles (usually focused on high schoolers), recipes, a response article, and an obituary.

The Public Library of Cincinnati and Hamilton County operates the Delhi Township Branch. The township first received a library in 1949 when a collection of books opened in Delhi Public School. A permanent library facility was dedicated in January 1968. In 1999, an addition added 5,000 square feet (460 m2) of space to the building, increased the size of the collection, expanded the children's area, added a glass reading room, and altered the landscaping. The branch was renamed to the Delhi Township Branch Library during its reopening and rededication.[18]
